The Archaean crustal evolution of the northern São Francisco Craton (SFC) reveals significant similarity with Kaapvaal-Zimbabwe and Pilbara, cratons, especially before 3.0 Ga. Likewise, compiled geochronological and Nd-Sr-Hf isotope data suggest that the Archaean blocks of the northern part of SFC (e.g. Gavião, Uauá and Serrinha) shared similar crustal evolution since 3.15 Ga. The 3.42–3.35 Ga TTGs of the southern and western Gavião Block have negative and slightly positive ɛ Nd(t)  and ɛ Hf(t)  values and T DM(Hf)  ages between 3.50 and 3.90 Ga, indicating that they were produced by partial melting of Eoarchaean to Palaeoarchaean crust, with minor mantle sources. The ca. 3.30 Ga high-silica plutonic-volcanic system, which is related to intraplate magmatism and intracrustal differentiation processes, would represent processes of continental rifting and break-up. In the northern Gavião Block, the 3.64 Ga migmatite-gneiss paleosomes with negative ɛ Hf(t) ,  176 Hf/ 177 Hf ratio between 0.2802 and 0.2805 and T DM(Hf)  ages between 3.75 and 4.15 Ga of the Mairi Complex represent the oldest dated rocks of the whole São Francisco Craton, suggesting late Hadean and Eoarchaean sources. The 3.15 and 3.00 Ga rocks of the Serrinha Block have positive ɛ Nd(t)  values, suggesting a predominant juvenile source. Likewise, coeval 3.15 and 3.00 Ga Uauá Block rock assemblage has slightly positive to negative ɛ Nd(t)  values, which indicate mixing of crustal and juvenile sources. The 2.90 to 2.77 Ga period in the SFC is characterized by pervasive crustal anatexis with high-K granite generation, similar to Kaapvaal and Pilbara cratons. Therefore, Archaean migmatite-gneiss terrains recorded four crustal differentiation intervals (e.g. 3.66–3.51, 3.45–3.30, 3.15–3.00 and 2.90–2.77 Ga) in the São Francisco Craton.
